Application of Industrial Switch in Intelligent Traffic Signal Control System

The traffic congestion in cities is related to the rapid growth of vehicles and pedestrian flow, but it is also related to the unscientific setting of signal lights and the insufficient utilization of road resources. The old-fashioned signal lights can no longer meet the needs of modern roads. With the continuous increase in the number of vehicles, it is urgent to upgrade the original signal control system to an intelligent traffic signal control system.

The intelligent traffic signal control system is a real-time networked control system for regional traffic signals that integrates modern computer, communication, and control technologies. It can achieve real-time control of intersection traffic signals, regional coordination control, and central and local optimization control.

As a component of the "Smart City", the "Intelligent Traffic Safety Management System Intelligent Signal Light Construction (Integration) Project" integrates data such as signal machines, coils, high-definition composite video detectors, queue length detectors, internet data, road construction, and police force distribution to form a closed-loop system of perception, judgment, command, and disposal, achieving traffic situation warning, traffic organization optimization, and signal timing optimization automatic event push can play an important role in intelligent traffic management, multi-channel security prevention and control, 24-hour scheduling response, and refined traffic guarantee.

Application Description of Our Industrial Switch

(1) The plan adopts a multi type interface industrial switch - a convergence switch, which enables nearby fiber optic convergence and access to the control platform for traffic light signals in different directions at intersections, thus achieving synchronous control of signals.

(2) On the one hand, the convergence switch connects the data return of front-end access switches in different directions at intersections, and at the same time connects all monitoring videos to the optical ports on the core switch through optical ports. Transfer to the superior monitoring sub center.

(3) The control center adopts a multi optical ports industrial switch, which can monitor and control the traffic light signals at multiple intersections, thus achieving synchronous signal control. Using Ethernet for transmission can achieve unified control and management, making traffic management more convenient and efficient. In this scheme, industrial switches with optical ports are used, and compared to the scheme of using media converters and all fast Ethernet switches, the transmission network is more stable and reliable.

Advantages of Our Industrial Switch Application

(1) The access ports of industrial switches include optical ports and electrical ports. Integrated design for switch processing. We have seamlessly connected and integrated digital video fiber optic transmission networks with digital video switching networks. Using Ethernet for transmission can achieve unified control and management, making traffic management more convenient and efficient. Ethernet switches come with optical ports, making the transmission network more stable and reliable.

(2) Supporting ring network redundancy technologies such as RSTP/MSTP ensures undisturbed switching of network communication, and the network self-healing time is less than 20ms.

(3) Adopting a managed industrial switch, in addition to providing convenient web and other access, it also supports SNMP and RMON management, facilitating unified management with third-party devices throughout the network.

(4) The industrial switch has passed the industrial level IV electromagnetic compatibility test to effectively prevent industrial interference: high-voltage AC electric field, electrostatic field, arc, thyristor, etc; Natural disturbances: lightning strikes, various electrostatic discharges, etc.

As a professional manufacturer of industrial switch, we assist in the construction of intelligent traffic signal systems, effectively improving the efficiency and service level of regional road networks, alleviating the current traffic pressure in the city, and striving to work for the orderly, safe, and clean city. In the future, we will continue to deeply cultivate the intelligent transportation industry, using advanced industrial Ethernet communication technology to achieve effective monitoring of traffic signals, ensuring the safety, reliability, and stability of the entire system, improving the efficiency of traffic maintenance and operation, and helping traffic to be safer, more orderly, and more intelligent!
